(Patchy
Hair Loss)
Patchy
hair loss or Alopecia Areata (AA) is a common hair condition in which one or
more bald (hairless) patches develop in the hairy regions of the body. The body
areas commonly affected by AA are the scalp, eyebrows, beard, moustache, and limbs
but any other areas might be affected. The patches may be restricted to one region
or might affect many regions simultaneously. The affected patch is usually
smooth and might be slightly depressed than the adjacent normal areas. Most
cases have no other symptoms other than the cosmetic concerns.
The problem is
known to affect all races and countries. It is estimated that in India alone
about one million new cases of AA arise every year. Most patients have little awareness
about causes, evolution, and probable outcomes of AA. A number of unscientific
and questionable remedies with potential of causing severe damage are known to
have been attempted by patients in search of a resolution. We believe that authentic
and trustworthy knowledge and appropriate treatment can help save effort and
money in a significant proportion of cases.
Quick
facts
- AA is a benign condition and does not
spread from one person to another.
- It is not caused by a defect of nerves
or brain function.
- It can arise in any gender and most
cases with most cases striking adolescents and adults.
- It is caused by a usually temporary defect
in immunity or one’s capacity to fight disease. A hereditary component has been
proved to be operative. It has been observed that AA can be accompanied by several
diseases caused by immunological defects.
- The hair follicle or the root in the
bald patch stays alive even after the visible part of hair is shed off. This
root is capable of regrowth. The fresh hairs growing as a result of recovery
process may at first be white or light in color.
- The course of AA is unpredictable. Every
case is unique in its response and a prediction about final outcome is not
possible.
Treatment
Options and Supportive Measures
AA patients should not panic as the
condition might resolve by itself without any intervention. They should handle
hairs very gently and avoid vigorous massage, hair styling, chemical treatment
or rough handling by avoiding frequent touching
Diagnosis of AA is usually straight
forward and is made on the basis of simple history and clinical examination. In
some cases, Trichoscopy or examination of scalp and hairs under magnifying
devices may be done. Other tests are rarely required.
The problem of AA might resolve by
itself as our bodies try to repair the defect in immunity. In cases where
treatment is necessary, a number of options are available which vary in their
mechanism of inducing repair. Some cases may recover better with simultaneous
use of a combination of multiple options.
Steroids, acting by way of suppression
of defective immune response, are the most effective drugs till date for
treating AA. Locally applied steroids are less effective than the injections
given into the patch. Derma roller, a less painful technique can also be used
for drug delivery into the patches.Orally administered steroids run a greater
risk of side effects and are used only in selected cases. Skin irritants that
produce a controlled injury or inflammation to modify immune mechanisms are
also used for AA to stimulate hair growth. Immuno-modulators are another group
of medicines known to hasten recovery. .
